If the nominal voltage is close to zero, put the trimpot between two larger value resistors to limit the range. At the same time, I would reduce the values so the total on each side of the wiper is still about 50k, to prevent offset drift due to input bias current drift. So, maybe a 10K pot with 47k on each end?
